SASE Framework MLOps Workflow
SASE Framework MLOps Workflow คืออะไร
SASE (Secure Access Service Edge) เป็น framework ด้าน network security ที่รวม SD-WAN, CASB, FWaaS, ZTNA และ SWG เข้าด้วยกัน ให้บริการผ่าน cloud เป็นหลัก MLOps (Machine Learning Operations) คือแนวทางจัดการ ML lifecycle ตั้งแต่ data preparation, model training, deployment ไปจนถึง monitoring และ retraining การรวม SASE กับ MLOps Workflow ช่วยให้ ML pipelines ปลอดภัย ควบคุม access ได้ทุกขั้นตอน และป้องกัน data leakage ตลอด lifecycle ของ model

เนื้อหาเกี่ยวข้อง — บทความที่เกี่ยวข้อง: overbought oversold คือ
A: SASE ดีกว่า: Zero Trust (verify ทุก request), identity-based access, ไม่ต้อง full tunnel VPN ข้อจำกัด VPN: all-or-nothing access, performance overhead, ไม่มี DLP/CASB SASE ให้: granular access (เข้า training cluster ได้ แต่ไม่เข้า production DB), inspect traffic, DLP สำหรับ remote ML teams: SASE เหมาะกว่า — ทำงานจากไหนก็ได้ ปลอดภัยเท่ากัน
